Hello everybody,
Another trivial change is turning into an insufferable waste of time.
As is customary, we solve it by maximizing the amount of people
wasting their time on the problem. Here it is:
sage: matrix.identity(15).plot(cmap='gray') # 1 is white and 0 is black
sage: matrix.identity(15).plot(cmap='Greys') # 1 is black and 0 is white
Sage's default is the first of those two:
sage: matrix.identity(15).plot() # 1 is white and 0 is black
I found it rather unpleasant that '1', the highest value, is the same
as the background color, when '0' is the most appearant color: black.
I opened a ticket to change the default, and of course somebody complained:
http://trac.sagemath.org/ticket/20026
I asked a lot of people around me (without hinting at my preference)
and everybody agreed that what #20026 implements is the most natural
choice. I let you decide, I'm bored at seeing that each line I
contibute to Sage means 3 hours wasted on senseless discussions.
